    Problems passing variables to include file.

    I don't know why I cannot get this to work. I want to include an external file in a script that produces an HTML table and is populated based on a few variables from the calling script. I thought php compiled in line, but after having no luck I tried executing the script by calling it by itself and it worked correctly filling itself with the correct SESSION variables. Maybe it's my syntax but I have tried Session variables, I think I used global correctly but I am not sure. I need to pass two items,
    [PHP]
    $imagenumber; // an image number in a variable called
    $_SESSION["directoryl ist"]; // (Which I split to get the correct path to the image)
    [/PHP]

      If you're including a file, that file inherits the variables of it's parent. Consider this:

      file1.php
      Code:
      <?php

define("HELLO", "Hello from file1");

include("file2.php");

?>
      and in file2.php
      Code:
      <?php

echo HELLO;
// would print: Hello from file1
?>

          file1.php
          [PHP]
          define("IMAGENU MBERCONST",$_GE T["imagenumbe r"]);[/PHP]

          And what's going on with the SESSION variable? I initialized my session but it doesn't want to pass the $_SESSION["home"] variable?

          include("file2. php");
          [PHP]
          <? ini_set("sessio n.cookie_domain ",substr($_SERV ER[HTTP_HOST],3));
          session_start() ;
          $_SESSION["home"];
          $dirlist = split ('\/', $_SESSION["home"]);

          // ***ABBREVIATED* *****
          echo'<img HEIGHT="100", WIDTH="60" src="http://www.website.com/';
          echo "$dirlist[1]/$dirlist[2]/tn_";
          echo IMAGENUMBERCONS T;
          echo'">';
          ?><html>
          </table>
          [/PHP]
          This gives me the incorrect path to the image:
          Just a moment...
          http://www.website.com///tn_IMAGENUMBERCONST

          As you can see the directories aren't present and IMAGENUMBERCONS T is a literal.

              IMPORTANT THING TO REMEMBER ABOUT THE include("xxx"); function!
              I was using the URL as a path to call the script when I should have been using the relative server path ie:
              [PHP] include("/home/4/4/a/2769/2769/public_html/file2.php"); [/PHP]

              NOT [PHP]("http://www.website.com/file2.php");[/PHP]
              The relative path works fine for including html for headers and footers and such but I guess all SESSION variables are not available when using this path even if you use [PHP]<? session_start() ;[/PHP]
              Which, by the way, I DID NOT have to use (session_start( );)in the included file's head.
              Thanks for the insight!

                  I don't see the point in using SESSION, as you're not actually leaving the page. But I think I'm not understanding something here..

                      could you please first change your include script path
                      from this:
                      Code:
                      include("/home/4/4/a/2769/2769/public_html/file2.php");
                      to this:
                      Code:
                      include("file2.php");
                      As I can see, you are using a shared hosting server right? (may not be too)
                      anyway no need to setup your path like /home/.... just give the relative path as i suggested.

                      let me have a closer look to your problem, as I also not sure about your question.
